Allen-Bradley 800FP-SM22 Maintained Selector Switch

Allen-Bradley 800FP-SM22 Maintained Selector Switch is a compact 22.5 mm plastic selector switch with a two-position maintained operator designed for control panels in industrial automation. It features a black operator with a white insert, a standard knob orientation, and a maintained action with a 60° switching angle, enabling reliable mode selection or start/stop control without continuous power to hold its position. Variants exist for different contact configurations; for example, the 800FP-SM22MX22 provides 2 normally open and 2 normally closed contacts, while the 800FP-SM22PX31 offers 3 normally open and 1 normally closed. The 22.5 mm round profile and plastic housing fit standard 22 mm control-panel cutouts and integrate with Allen-Bradley 800F family accessories. Common applications include panel-mounted control for conveyors, packaging lines, and general machine control where a discrete, latched selector input is required.
